What Our Gearhead(R) Experts Are Saying:"I've been riding in the 9in version on hot, technical trails, and it's my go-to length. It offers great coverage without feeling bulky, and the ventilation really shines on long climbs."When rides get longer and the heat starts to build, we want shorts that disappear once we're on the bike. The OPR 9in Short is built by Stio for demanding mountain rides where airflow, freedom of movement, and comfort matter just as much as durability. The 9-inch inseam hits a balanced sweet spot for coverage and mobility, making it easy to stay focused on the trail ahead. Built with Pertex Equilibrium NetPlus fabric, the OPR 9in Short manages airflow while standing up to abrasion from saddle time and trail features. Four-way stretch and an action gusset allow unrestricted movement through technical sections, while perforated panels at the waistband, pockets, and inseam improve ventilation in high-heat zones. A contoured waistband with an integrated belt system keeps the fit secure through constant motion.
